How Climate Change Is Affecting Fall Foliage

The video discusses how autumn is a beloved season in the US, but climate change is altering its characteristics. Warmer temperatures extend summer, affecting the timing and vibrancy of fall foliage. This impacts tree cycles, photosynthesis, and even causes some trees to migrate. The economic implications are significant, as foliage tourism is a major revenue source. The video highlights the complex interplay between climate change and natural ecosystems.

What is the main reason for the delay in the timing of fall foliage colors?

• Increased rainfall

• Decreased sunlight

• Warmer weather lasting into autumn

• Higher wind speeds

How does climate change affect the photosynthesis process in trees?

• It creates wetter and warmer conditions impacting photosynthesis

• It causes trees to produce more oxygen

• It reduces the need for sunlight

• It increases the amount of chlorophyll produced

Which color in the fall foliage is most affected by climate change?

• Green

• Orange

• Yellow

• Red

What is one potential ecological impact of climate change on trees?

• Trees will become shorter

• Trees will grow faster

• Trees may migrate north through seed dispersal

• Trees will produce more fruit

How much revenue does leaf tourism generate annually?

• $10 to $15 billion

• $25 to $30 billion

• $40 to $50 billion

• $5 to $10 billion
